You want to route traffic from LAN network to an IP assigned to the WAN That makes no sense.

I think what you're trying to achieve is, that traffic from LAN to the internet is shown as if it is coming from X.X.X.44 outside, which is an alias on the WAN interface. That's NAT.This can be done by outbound NAT in pfSense. Firewall > NAT > Outbound.Set it in the hybrid or manual mode at first. Then add a rule:Interface: WANsource: LAN netdest: anyTranslation address: X.X.X.44

Yes that is exactly what I meant, thank you for correcting my explanation and for providing a solution, I was wondering if it is possible to assign a public ip address directly to a server on my network, without NAT, while retaining the firewall can this be achieved do you know how or do I need to start a new post.

You can achieve this by bridging WAN and LAN interface. But this way you can only use the public /29 subnet on LAN. pfSense is still able to filter traffic, but not to forward anything, of course.If you don't have special reasons for bridging it isn't recommended.
